Demobilisation is the process of disengaging individuals or groups from social or political movements. Factors influencing demobilisation include success or failure, repression, co-optation, and internal conflict. Demobilisation can occur through individual disengagement, collective dissolution, repression, or co-optation. The consequences of demobilisation include loss of momentum, political apathy, repression and backlash, and fragmentation. Understanding demobilisation is crucial for sociologists studying collective action and social change.
